BUG: Snapshots

1
the Slideshow does not work using the dashed version. making a macro to quickly open up a slideshow does simply nothing, when i select string giving the snapshots a name like 1 without space which seems to be the only naming possible it ignores it completely, neither space nor enter works to complete.

2
when i open the slideshow from the properties panel, viewport navigation does not work anymore

3
the floating navigation disappears when i hit stop, would be good to keep it floating to reinvoke the slideshow.

4
the snapshots stay greyed out till i hit forward for the first time, then it unlocks the different snapshots, its not optimal.
